Anything can be done about an ugly gouge / scrape on a royalex canoe?

I was paddling in Hitchens Pond 2 weeks ago and my friend did not see a rock near the surface and we hit it pretty good, scraping down the length of the canoe. I figured it would be like all the rest of them over the years, mostly just unsightly and cosmetic and underneath the water, not seen while paddling...but when I got it back up on the roof of the car it was a pretty nasty one. I don't think it penetrated the interior but I don't like it. Can anything be done about it?

A tripping canoe is pretty much a floating barge anyway, probably will have no effect on performance...but I'd sure like to get rid of this ugly scrape!
